Abstract

In the present work simulation of impact response using LS-DYNA explicitfinite element code is described to investigate the crash behavior and energy absorption characteristics of square glass fiber reinforced plastic tubes, subjected to impact load. Filament-wound tubes with two layers [+45º, -45º] were fabricated and tested. The experimental crushing characteristics data are compared with the obtained numerical results, showing good agreement. The effect of geometrical parameters, winding angle and the failure mode on the energy absorption characteristics are also investigated.
